Product Details

The AD573 is a complete 10-bit successive approximation analog-to-digital converter consisting of a DAC, voltage reference, clock, comparator, successive approximation register (SAR) and three state output buffers- all fabricated on a single chip. No external components are required to perform a full accuracy 10-bit conversion in 20 µs.

Operating on supplies of +5 V and -12 V to -15 V, the AD573 will accept analog inputs of 0 V to +10 V or -5 V to +5 V. The trailing edge of a positive pulse on the CONVERT line initiates the 20µs conversion cycle. DATAREADY indicates completion of the conversion. HIGHBYTEENABLE (HBE) and LOWBYTEENABLE (LBE) control the 8-bit and 2-bit three state output buffers.

The AD573 is available in two versions for the 0°C to +70°C temperature range, the AD573J and AD573K. The AD573S guarantees ±1 LSB relative accuracy and no missing codes from -55°C to +125°C.

Three package configurations are offered. All versions are offered in a 20-pin hermetically sealed ceramic DIP. The AD573J and AD573K are also available in a 20-pin plastic DIP or 20-pin leaded chip carrier.

PRODUCT HIGHLIGHTS

The AD573 is a complete 10-bit A/D converter. No external
components are required to perform a conversion.

The AD573 interfaces to many popular microprocessors
without external buffers or peripheral interface adapters. The
10 bits of output data can be read as a 10-bit word or as 8-
and 2-bit words.
